Airway parameter calculation

In the CIP module, select the airwayinspector to calculate the relevant parameters. After selecting the location, the calculation result cannot be generated%KV2Z2I~{L}R)8M@}LAZV)0

Before calculating the parameters, I have extracted the centerline of the airway, and used the CROSS-SECTION in VMTK in version 4.11 to select a plane orthogonal to the centerline. It is precisely because of this that the airway parameters cannot be calculated. Situation, but I don’t know where the problem is. Has anyone encountered this situation before? Can you explain me something?
